Subject: NVMe: Initialize device reference count earlier

From: Keith Busch <keith.busch@intel.com>

commit fb35e914b3f88cda9ee6f9d776910c35269c4ecf upstream.

If an NVMe device becomes ready but fails to create IO queues, the driver
creates a character device handle so the device can be managed. The
device reference count needs to be initialized before creating the
character device.
